AAA Inventory Item Design with Data-Only Blueprints | Unreal Engine 5 Guide | EP - 57
In this episode, we take Unreal Engine 5 inventory design to the next level by building a data-driven, modular item system using Data-Only Blueprints.
Learn how to separate logic from data like AAA studios do — making your inventory faster to scale, easier to maintain, and fully designer-friendly.
We’ll cover how to:
🟩Design a flexible Inventory Item Base Class
🟩Create Data-Only Blueprints for new items without writing a single line of code
🟩Store and modify static, mutable, and actionable data efficiently
🟩Understand why composition beats inheritance for item design
🟩Build a clean foundation for scalable, multiplayer-ready inventory systems
Whether you’re working on an RPG, survival, or shooter, this episode will teach you the AAA mindset behind data-oriented design in UE5.
